The scorecard is released biennially. Overall, the Legislature was ranked as “below average” for protecting Michigan’s natural resources. Democrats scored better than Republicans in this session’s Legislature, which has Republican majorities in both the Senate and House.

“While none of our elected officials received a zero, very few received a perfect score, either,” Lisa Wozniak, executive director for Michigan League of Conservation Voters, said in a statement. “We were able to find unanimity on issues such as invasive species but there continues to be a devastating lack of real champions for Michigan’s Great Lakes, air, land, water and wildlife.”

Lawmakers in the state House averaged 48 percent. Rep. Tim Greimel, D-Auburn Hills, had a perfect score but his voting record is incomplete because he’s serving a partial term. Many other Democrats scored high on the group’s scale, but were downgraded for voting against extending a fee collection deadline for the Department of Environmental Quality as part of their opposition to a broader budget package in 2011. The highest score for Republicans in the House was 46 percent, shared by Holly Hughes of Montague, Matt Lori of Constantine and Wayne Schmidt of Traverse City.
